Скачать или смотреть Extracting or Pulling Bundle of Shell &Tube Heat Exchanger by the Puller, Crude/RCR Heat Exchanger.

--- A heat exchanger bundle:
is typically removed from its shell by a pulling car or sled of the extractor that exerts a pulling force on a tube sheet which is fixed to the ends of the tube bundle



General:
Tube bundle heat exchangers are primarily suited for heat transfer between various liquids and gases with or without phase change. Excellent results have been obtained using water, thermal oil, wet steam etc. to warm or cool liquids and gases. The standard series consists of 6 sizes with heat transfer surfaces ranging from 0.5 to 500 m2.




Range of application
Tube bundle heat exchangers have a great versatility in their use and are applied in different branches of the industry, e.g.:

• Power station technics
• Machine industry
• Gear manufacturing
• Chemical Industry
• Process engineering

Design and Function
The heat exchangers consist basically of housing and tube bundle. The housing is a welded construction and includes all connecting, joining and fastening elements. The standard smooth tube bundle to be installed is a two-way model. The exchanger design variation with U-tubes (U-design), the variation with the floating tube base (D-design) or with a fix compensator (K-design) all of them allow for large changes in length between the casing and the tube bundle due to heat expansion.

Materials
The following material combinations are possible (special materials on request):
Casing tube: Steel St37-2, St37-2 galvanised, stainless steel V2A/V4A
Lid: Steel St37-2, St37-2 coated with RILSAN, stainless steel V2A/V4A
Cooling tubes: SF-CU, CuZn20Al, CuNi10Fe, CuNi30Fe, stainless steel V2A/V4A
